(54) | Rotary laser emitting apparatus |
(57) A rotary laser emitting apparatus (10) includes a rotary body (12), a foundation
(11) configured to rotatably support the rotary body about an axis (Ra), a laser light
emitting section (41) contained in the rotary body and configured to emit laser light
(Lm) in a direction orthogonal to a rotation axis of the rotary body, a relative slope
detecting mechanism (48) configured to detect an amount of deviation of the rotation
axis of the rotary body from the axis of the foundation as a relative slope signal,
and a transmitting section (47) configured to transmit the relative slope signal detected
by the relative slope detecting mechanism.
